PLOW."

- i To all whom) it ma concern:

' citizen of the United States, residing at McFall, in the county of Calhoun and State of Alabama, have invented certain new and a useful Improvements in Plows, of which the following is a specification. 1 This invention-relatesto animprovement in plows. r a v The primary object 'ofthe invention is to provide a plow in whichthe plow standard may be conveniently adjusted to dispose the plow at various angles, and in which the adj ustment" may be secured without detaching the standar A further object of the invention is to provide a construction in whichthe beam and the supporting structure for the standard may be conveniently assembled, and which, while permitting the standard to be readily adjusted, will be as substantial as the usual form of non-adjustable plow.

i jFor a full understandlng ofthe invention,

reference is to be had tothe following description and accompanying drawing, in wh1ch:' i

. Figure '1 is a perspective viewfof the plow beconstructed ofwood, although the same with the various .partsthereof in operative assembled relation to each other. Fig. 2 is a disassembled perspective view of the plow standard and its supporting means. Fig. 3 is a detail view showing,partly in section, the rack bar and block by which the standard is held in adjusted position, Fig. 4 is a detail perspective view of the plates which are secured to the plow beam and which serve to pivotally support'the plow standard in the desired relation to the beam.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawing by the same reference characters.

In the drawing, 10 designates the plow beam which is curved as at 11, the terminal 12 being curved again as at 13 to form an extension 14 which is curved as at 15, there-' by providing a crotch 16. This beam may is preferably formed of metal.

A supporting plate or arm 17 is secured to each side of the beam, said plate conform ing to the shape of thebeam from the point 18 to the point 12. These plates 17 are secured to the beam y, b lts 19 which p s Specification of Letters Patent.

rear terminal of the plow beam are bolted or otherwise secured a pair of plow handles 24 which may be of any desired construction asregards their general outline. However, these handles differ from the ordinary handle in that they are provided on their inner faces and adjacent their lower terminals with recesses which are adapted to receive the fork arms of a rack bar to be hereinafter described. The foregoing description will be readily appreciated when reference is had toFig. 1. I

:Theplow standard consists of a plurality of spaced plates 25 which are recurved longitudinally. .A plate 25 is arranged on each side of thebeam, a pivot pin 26 passing through the plates and the terminals of the rations of the block 30. Theterminal 33 of the rack bar is bifurcated, the bifurcations 34 embracing the portion 14: of the beam, and extending within therecess 23. A pivot bolt 25 passes through the handles 24:, member 14 and members 34. A coiled spring 36 is supported by the handle at 37, said coiled spring being connected at 38 with the rack bar, normally maintaining the rack bar in contact with the block 28.

It will be noted that when it is desired to lock the rack bar against movement, the feed screw 29 may be moved in contact with said bar, thereby forcing the teeth of said bar in contact with the serrated face 31 of the block 30. When itis desired to adjust the plow standard, the screw 29 is brought out of contact with the rack bar, the spring 36 drawing the bar away from the serrated face of the block 30. The plates 25 which ponstitutethe standard maybe moved on the teeth 26, and the plow adjusted at any angle.

After the standard has been adjusted, the screw 29 is manipulated to force the teeth of the rack bar in contact with the block 30. By this construction, it will be noted that the plow may be adjusted at any desired angle, in a simple and convenient manner.

It will also be seen that the entire structure is such as may be easily and economically manufactured, and that the members which constitute the support for the plow standard form a reinforcing means for the plow beam.

hat I claim is 1. A plow including a longitudinally recurved beam, a plate arranged on each side of said. beam, said plates being terminally connected, a pair of spaced plates disposed one on each side of the beam and pivotally supported near the terminals of the firstmentioned plates, and means for locking the last-mentioned plates in adjusted position. 2. A plow including a longitudinally re-- curved beam, a plate arranged on each side of said beam, said plates being terminally connected,.a pair of spaced plates constituting the plow standard arranged one on each side of the beam,-said plates being pivotally supported by the first-mentioned plates, I blocks'arranged between the plates and. I

pair of spaced plates, disposed one on each' side of the beam, said plates being pivotally connected to the first mentioned plates,

bopies of this patent may be obtained for blocks supported in spaced relation-between the second-mentioned plates, a curved, rack bar one terminal of which is bifurcated, the bifurcated terminal of said rackibar embracing said beam, said rack bar extending between the said blocks, and, coacting means carried by the blocks for supporting the rack bar against movement. i Y

4. A plow including a longitudinally re-. curved beam, a plow standard consisting of spaced plates, disposed one, on each side, of

the beam means carried by the beam for pivotally supporting the plates, spaced blocks interposed between the plates, the

lowermost of said blocks being formed with a serrated face, a'curyed rack bar pivotally connected to the rear terminal of the beam and disposed to extend between said plates, yieldable means for normally holding the rack bar in spaced relation to the lowermost block, and, means carried by the uppermost block for forcing the rack bar in contac with the lowermost blocln 5. A plow including a beam, a plow standard pivotally connected to the beam andineluding a pair of spaced plates disposedon opposite sides of the beam, each of said 'plates including' an intermediate straight portion andterminal curved portions, and

means carriedby the rearterminal of the beam for holding the standardin adjusted position. j

6. A plow. including a beam, a standard pivotally connected thereto, said standard including apair of spaced places disposed.

on oppositesides of the beam, each offjsaid plates being'bent toproduce a straight intermediateportion, and curved offset terminal portions, and means pivotally attached to the rear terminal of the beam for'holding thestandard in adjustedposition.
